Definition of electron lens in English: electron lensnoun Physics A device for focusing a stream of electrons by means of electric or magnetic fields. Example sentencesExamples - The technology, called aberration correction, fixes imperfections on the microscope's electron lenses.
- An even better way is to step an acceleration or retardation voltage in an electron lens mounted in front of the energy analyser.
- Ruska knew that electrons could be manipulated within a magnetic field, and in the late 1920s, he designed a magnetic coil that acted as an electron lens.
- An electron lens is used for focusing electrons from a cathode to an anode.
